What is the passenger capacity for a C-17 on the centerline seating?

The passenger capacity for a C-17 on the centerline seating is indeed 48. This configuration allows for efficient use of the aircraft's space while ensuring that passengers are securely seated. The C-17, primarily designed for military logistics, can accommodate different types of cargo and personnel, but centerline seating specifically optimizes the number of personnel it can carry in a designated area while maintaining safety and comfort.

In this layout, the seats are arranged along the centerline of the cargo compartment, allowing for quick deployment and easy access to the rear ramp when necessary, which is particularly useful for rapid troop movements or logistical operations. In contrast, the other options represent higher capacities that may refer to different seating configurations or a combination of seated and standing personnel in other areas of the aircraft that are not in the centerline seating configuration.
